Renewable energy is no longer a thought or goal for the future, but a rapidly increasing part of the present. We are all looking to be a more Eco- friendly energy choices, but that should not be our only reasons for looking to other energy sources, and fast. Our government is in support of green energy and providing funding for projects, but we are responsible for doing our part as well. Read on and find out why the time has arrived to get renewable energy now.

We have finally come to the point where it is do or die, so to speak. Before there is a major crisis, we should be prepared. Strength lies in the ability to provide alternatives in adverse situations, and if you have them, then you are strong. The more alternative energy sources that we have, the stronger our nation will be. There are five different type of renewable energy available to us, solar, wind, geothermal, biomass, and hydropower.

It seems that we are making some steps toward our goal for the future with the help of the government. The Office for Energy Efficiency and Renewable Energy (EERE) federally funded two point two billion dollars in 2009 for different projects related to renewable energy. These projects involved universities, businesses, industries, etc. The goal will be long term before we can expect to see solar panels for electricity in every home and apartment complex, but we are making strides.

Hydropower can be counted for over seventy percent of our total renewable energy. The process itself is really simple. Water is directed or flows through piping which is called penstock. The penstock then turn a generator which produces electricity. The Hoover dam is an example of hydropower turned into hydroelectricity. It was build in 1936, and is the largest electric generating system in the world.

The sun can provide us with energy for electricity and heat. Energy that we get from the sun for heat is known as solar thermal. When it is taking sunlight and directing it into mirrors or lenses to generate electricity, it is known as a high temperature collector. There are also low temperature collectors which can be used to heat pools, and medium temperature collectors which are used to heat homes and larger buildings. These collectors are photovoltaic cells which use the radiation absorbed from the sun in the same way that electricity is created.

Wind power is another great benefit and another simple process. The motion of the wind is converted into mechanical energy by a wind turbine, which generates electricity. Wind power is being used regularly now in California and Texas. It also has the benefits of giving off no greenhouse gases while producing energy.

Geothermal power is much different that solar thermal power. It has to do with trapping heat that is underground, and building energy from the trapped heat. The heat being tapped into is actually coming from the core of the earth. It can be closer to the surface in some areas, which makes it easier to harness. It is harnessed by the trapped heat naturally creating steam, and then the steam being used to turn a steam turbine.

Biomass is a natural storage system here on earth for electric power. The plants have actually been storing the energy of the sun for us, and when they are burned, you have energy. Power plants that are operating on biomass fuels use boilers that heat water to operate turbines creating electric power.

We are not short on options, but we are getting shorter on time. We have made great strides in the advancement of renewable energies and continue to look into them for our near future. We should consider them a part of our nearest future because green is not the only reason we should get renewable energy now.
